InRange beeping once battery is inserted

After a couple of other problems with too many disconnects I ran into a situation where the InRange starts beeping (about 1 sec of tone followed by 1 sec of pause) forever. Only option was to remove the battery.

Even after leaving the battery out for the whole night it's all the same this morning. Same when using the replacement battery instead.

Once again tried various things, but no success. The InRange app finds the device, it's just hard to bear the beeping for minutes while the app searches and tries to connect. But after finding the InRange it cannot 'pair' with the device and the app suggests to start over.

Of course also made sure it's gone from the Bluetooth settings, also removed and reinstalled the app, nothing helps.

Unfortunately I have to assume that this product is crap. Did not even work for one day and during that day had many false alarms.

How come this constant beeping behavior is not documented? Even if it's an error state it should be documented in the manual.
